Abstract: To provide a method of efficiently separate protective components of Bordetella pertussis. On the basis of differences in adsorbability to calcium phosphate gel formed by adding calcium ions to a Bordetella pertussis culture in the presence of excess phosphate ions, protective components of Bordetella pertussis are separated from the Bordetella pertussis culture.

Abstract: A PBX, when notified information of an originating manipulation such as dialing of a receiver's number from a keyboard connected with a PC, judges whether an origination request is from the PC or a first terminal. In a case of the request being from the PC, the PBX performs number analysis processing of the PC which is the originator. The PBX judges whether there is information about a terminal associating with the terminal requesting the origination, and when there is information for the terminal, performs to connect with the associating terminal, and processes the origination request to thereby connect with the counterpart terminal. When there is no information about the terminal, the PBX processes the origination request as usual to thereby connect with the counterpart terminal.
